LAMP.

Specification of Letters Patent No. 26,295, date November 29, 1859. i

To all whom it may concern:

Be it known that I, C. IV. RICHTER, of

. Madison, in the county of, Morgan and State ofGeorgia, have invented anew and Improved Lamp; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe annexed drawings, making a part-of.

this specification, in which Figure 1, is a sectional elevation of myinvention. Fig. 2, is a horizontal section of the same, taken in theline as, m, Fig. 1. Fig. 8, is a horizontal section of the same, takenin the line y, y, Fig. 1.

Similar letters of reference indicate correspending parts in the severalfigures.

The object of this invention is to obtain a lamp for burning the heaviergrades of coal oil with a good illuminating flame.

The invent-ion consists in a novel means employed for adjusting orraising and lowering the wick within the wick tube, so that the wick isallowed to remain loose and free from pressure within the tube, therebyfavoring the capillary ascent offthe ,viscid oil and lnsuring a propersupply of the same to the flame.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it. e

A, represents the body and font of the lamp, which may be constructed inany of the known ways, and B, is the burner which is .screwed into thetop of the font as usual. This burner B, is the one most generally usedfor burning coal oil and known as the Vienna burner it being suppliedwith three sets of perforations a, b, c, as shown clearly in Fig. 1,which supply the flame with air both at the inner and outer side.

of the cap 03.

The wick tube e, may be constructed and arranged as usual but the meansemployed for raising and lowering. it is different.

This device is formed of a short bar 7, which is slotted transversely asshown at f, and.

has a fulcrum pin 9, passing through the slot. At the inner end of thebar f, a toothed plate 1", is attached the form of which is shownclearly in 3. I11 the tube 6, and opposite the toothed plate 1, a slots, is made, shown in Figs. 1, and 3. The bar f, projects through a slot25, in the side of the burner and when the wick a, in the tube 6, isproperly adjusted the bar f, is drawn outward so that the toothed platewick is to be adjusted the; barf, isjshoved 7, will be free from ,thewick. This resultfi 1 is permitted on accountof the slot f, throughwhich the fulcrum pin g, passes. Whenthe j j inward so that the platefr,will be in con-j tact with the wick andthe lattermay consequently beraised and lowered by operat-Q ing the bar f, on its fulcrum pin.Bythisf device the wick n, is not compressed as is the case where theusual toothed pressure wheels are employed and;consequentlythe}, j 1,oil is allowed to ascend freely up thefwick.
